Dolphin mailbox and other mailboxes in Mailbox Picture Collection

I always like to look at the Sam's Mailbox Picture Collection http://sblom.com/mailbox/

This collection has very funny novelty mailboxes, for example unusual dolphin mailbox, whale mailbox, train mailbox, golf mailbox, airplane mailbox, flamingo mailbox, motorcycle mailbox and so on. Some of these mailboxes people can buy, for example at http://mailbox-plaza.com/. But some of these mailboxes apparently were made by the owners.
